You can go to this web site to view all the versions and features of the AeroForce Interceptor guages. What I like about it is that it's a simple plug and play unit. It plugs right into the OBD2 port under the steering wheel. It's all digital read out and is programmable with many optional parameters including a shift light. Some of the many features they have is the ability to monitor mph, rpm's, hp, torque, air/fuel ratio, fuel injectors, fuel level, fuel mileage, recording feature to record all your stats such as 1/4 mile and maximum speed, transmission temp, oil temp, coolant temp, ambient air temperature, engine load, and much...much more.
